Beveling Holes
I've read on this forum that beveling the edges on holes drilled in the gelcoat will help prevent spider cracking. Can someone explain why that is? I've drilled many holes in my gelcoat for various things but did not bevel any of the edges. I drilled in reverse so as not to chip the gelcoat but did not go back and bevel the edges afterwards, and am wondering if I should go back and do it.
Thanks,

Often you use a slightly larger bit, rotating in reverse by hand (same as you did when drilling the initial hole). You can also then use some sand paper to rub off the edge even more.
Page 8 of the Monster Tower install has a nice graphic to describe it:
